Comparison of Intranasal Kovacaine Mist, and Placebo for Anesthetizing Maxillary Teeth in Pediatric Patients

Detailed Description
The study will employ a multi-center, randomized, double-blind, placebo-controlled, parallel-groups design to demonstrate the safety and efficacy of Kovacaine Mist delivered intranasally for inducing pulpal anesthesia of maxillary permanent teeth numbers 4 to 13 (maxillary right second premolar to maxillary left second premolar) or maxillary primary teeth numbers A to J (maxillary right second primary molar to maxillary left second primary molar) sufficient to allow completion of the Study Dental Procedure. The maxillary teeth will be categorized in two subsets, anterior teeth (permanent teeth numbers 6 to 11 and primary teeth numbers C to H) and posterior teeth (permanent teeth numbers 4, 5, 12, 13 and primary teeth numbers A, B, I, J).
The intent is to treat 90 male and female subjects aged 3 to 17 years, inclusive, at 3 study sites, 2:1 randomization within each study site, and an overall goal of 60 subjects treated with Kovacaine Mist and 30 treated with placebo. Subjects will receive Kovacaine Mist or placebo (2:1) according to the kit randomization plan within three dosing strata (100 µL, 200 µL or 400 µL) based on subject weight at entry: subjects weighing 10 to <20 kg, 20 to <40 kg and ≥ 40 kg will be assigned to the 100 µL, 200 µL or 400 µL dose group, respectively. Recruitment will be from diverse pediatric dental patient populations. To ensure adequate representation in the 3 dose/weight groups, each stratum will contain at least 25% of subjects.

Exclusion Criteria:
- Having received dental care requiring a local anesthetic within the 24 hours preceding study entry.
- History of allergy to or intolerance of tetracaine, benzyl alcohol, other ester local anesthetics, or para-aminobenzoic acid (as found in PABA-containing sunscreen).

- Use of a monoamine oxidase inhibitor within the 3 weeks preceding study entry.
- Nursing, pregnant, suspected of being pregnant, or trying to become pregnant. (Females of child-bearing potential will be required to undergo urine testing on the day of, but prior to, study drug administration to rule out pregnancy.)
- Inadequately controlled thyroid disease of any type.
- Having received any investigational drug (including Kovacaine Mist) and/or participation in any clinical trial within 30 days of study participation.
- Frequent nose bleeds (≥ 5 per month).
- History of congenital or idiopathic methemoglobinemia.
- Presence of an upper respiratory infection and/or fever defined as body temperature ≥100.4° (38°C) on the day of and prior to study drug administration.

Results of Naris Examination (NE) - Patency and Ulcerations
Time Frame: 120 minutes post drug administration
|
The investigators evaluated the treatment naris for patency and ulcerations. Patency was evaluated as followed: The nostril not used for dosing study drug was manually occluded and the subject was asked to sniff gently. Airflow in the naris was used to determine if it was patent (yes) or not (no). For ulcers, the investigators performed a visual examination for the presence of ulcers and recorded if they were present (yes) or not (no). |
